• Unit serial number
• Current model option (before memory upgrade)
• Desired model option (after memory upgrade)
• Unit MAC address (available in the identification label)
Once the upgrade parameters have been entered, press the
“Upgrade Firmware”
button. When communication has been
established, the program will show a message requesting to turn off and back on the relay to continue with the upgrade
process.
Once the relay has been turned off and on, a new screen allows selecting the folder that contains the firmware upgrade
files (“upgrade.txt” file must be located in this folder).
This Upgrade.txt file is located in the folder where the desired
firmware upgrade files are. This firmware upgrade files can be found in the Multilin web site.
If the files are downloaded from the web, they are compressed in a zip file. It should be decompressed in a temporary
directory from which the upgrade.txt file will be selected.
Once the Upgrade.txt file is selected, the “
Upgrade Firmware
” button will be enabled. Press this button to initiate the
process. During the process, the program displays the files that are being upgraded. When the files transfer is finished, a
message appears informing that it is necessary to wait sometime before resetting the unit, in order to start working with the
new firmware version in the relay. When the whole process has finished a message will be displayed asking to switch the
G650 on and off.
At this point, the firmware upgrade procedure is finished and the relay is ready to be powered down and back up to check
that the firmware has been upgraded properly.
When upgrading the firmware the entire settings and relay configuration are reset to factory default value.
Once the equipment has been properly checked, the G650 is ready to be used.
Remember that calibration settings and configuration must be loaded to the relay. To recover the relay calibration:
Go to EnerVista 650 Setup main menu:
Communication > Calibration > Set calibration Settings
to store in the relay the calibration settings if necessary.
For firmware versions 3.20 and higher ones, it is advisable to calibrate the offset in order to avoid measurement errors in
RMS values. Go to
Communication > Calibration > Offset calibration
to recalibrate the offset in the relay if necessary (if
RMS values do not show zero with zero inyection). To calibrate the offset the values for currents and voltages must be zero.
File > Config file (*.650) Converter
to convert the setting and configuration file *.650 for the relay (if is was in a previous
version format) to the new version (see section 3.1.7.2 in human interfaces in this manual)
File > Send info to relay
to send the new settings and configuration file to the unit.

ETHERNET CABLE FOR HUB OR SWITCH) .
3. GET CALIBRATION SETTINGS (AND SAVE IT TO A FILE).
4. SAVE ALL THE DATA FROM THE RELAY (SETTINGS, OSCILLOGRAPHY, EVENTS).
5. FROM THE ENERVISTA 650 SETUP PROGRAM SELECT "
